LS2 Exhaust Headers

[gtrsimon]

Started the exhaust system for the LS2 just getting prices now for pre cut tube so hope to be welding in a week. Cad drawing below (hope they fit).

Num 3 should just be reaward of engine mount, near side no a problem as head offset gives an extra 25mm. Have also moved 1 + 2 out a bit to balance the lengths not sure how important it is. Not much room between collector and engine / chasis so hope engine does not move too much on mounts.

I am going to tack them up then get them welded (got to look right) expect I will ceramic coat them to keep heat down. if all goes well will look into having them made, if anyone is intrested complete set including Cats should not be much more than Ultima ones.

Here's an update on the headers.
the parts came at lunch time

dry built one side up ready for tack welding

fitted to car


NS was easy no mods required, OS was a bitch had to mod some tube to miss engine mount but got there in the end. Now waiting for the Exaust boxes and cats to come expecting them thursday so when system fully tacked up will take it to someone who can weld!!

The headers will fit LS1 LS2 , AFR heads but not LS7 as these have a slightly different port layout(so I am told).
could supply kit of bits or finished headers just need to amend drawing a bit first to clear OS engine mount better. Email me direct for more info.

Never quite sure what you include in this measurement eg to the collector point, the tubes are aprox 17" and all the same length within 0.25" would have made them longer but not the room Regards Simon
